My games lag after 5 mins in game it lag for a couple of seconds like 10 and then stops the process repeats itself over and over again big lag :( 
only seems to lag on demanding games left for dead 2 Mass Effect 2 games like that works fine

my system specs windows 7 64 Bit

Motherboard: ASRock N68C-S UCC
Processor: amd phenom ii x2 555 unlock 4 cores 3.2GHz
Video card: ATI XFX 6870
Ram: 4GB DDr3 1333
Sound card: Creative Sound Blaster X-Fi Titanium
Power supply: 630W
Hard drives: 2 7200RPM 1 5200 rpm Drive

Things I did that didn't work :fou: 

reinstall windows
uninstall antivirus AVG
defragment hard drives
change video card to a nvidia GTS 250
clean up registry errors
update drivers catalyst 11.9
CPU temperatures are low 55c max
GPU temperatures are low 85c max

Games that are lagging

Battlefield Bad Company 2

85C isn't actually low, it's rather high.
The reason for stuttering is that your card is overheating. What are the temps while at idle?

CPU temps are okay.
Check if the card has got any sorts of dust piled up. Check if the heatsink is loose. :)

that can't be the problem the maximum temperature for that card is can is 105c on the amd web site
and for the dust piled I bought the card a month ago i have dust filter in my computer i don't think the heatsink is loose I don't hear any shaking

Yes, maybe for the "generic" 6870 card, those temps listed on AMD website are the norm. But you have to take into account that there are a lot of GPU manufacturers, with different cooling solutions and slightly different temperature thresholds. Some of the cards might actually run too hot at 85 degrees, while others might cope better at those values.

To be honest, to me too it seems those temps are a bit too high, mate. And if a card is running too hot, it may not always be the heatsink to blame.

AMD's website shows the temps of their cards max temp. You have got it from another distributor.
Either ways, 85C is really a high temp and you could be risking permanent damage!

Artifacts do appear when the GPU is overheating. But stuttering is the first thing that happens.
Did you see if the GPU heatsink is closely attached? Does it have any sorts of dust?

No i didn't see any sorts of dust the card seem to be pretty tight to the heatsink how do you know if its loose this started happening on day 1. I bought the GPU a month ago I thought it was the driver (11.8) so i waited a month update to (11.9) didn't fix the lag

I remember doing that it didn't work. is it possible the card is defective? i remember reading a form that had the same problem he find out it was his motherboard that was Causing his games to stutter can you guys look up my motherboard to see if is good or not (Motherboard: ASRock N68C-S UCC) it has pci express X16 NOT pci express 2.0 maybe the bandwidth is too slow for some game which makes some of my games stutter. the link to my Motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E168...

try turning off power saving mode in bios and the desktop power settings.
add a few hundred mhz to the cpu and see if it balances out.

i found i had to bump my i7 to 3.2 to stop in game stutter on cod 4. some other things that can cause games to stutter...
time update sync (turn it off from contol panel)
incompatible mouse drivers.
unstable INTERNET connection... (try optomizing it)
to high fps. increase in game quality settings. (anything over 120 fps should be considered high fps).

I agree that if drivers have been ruled out as a cause then the next most likely problem is vSync. This is supported by your observation that it only happens in demanding games. If you have your graphics settings adjusted so that most of the time the framerate is more than 60fps and only drops below in demanding scenes of demanding games you will get this effect. My understanding of vSync is that as long as your card can keep the framerate above 60fps you won't have a problem (good if the framerate is too high and produces tearing) but as soon as it drops below 60fps the way frames are buffered will cause the framerate to be almost exactly half of the cap. If you monitor the framerate with FRAPS and it drops suddenly from 60 to 30 but doesn't spend much time between then it likely is a vSync issue. I had the same problem quite a bit in games that won't let you disable vSync when I was running a single 6870 because they can't always keep the framerate above 60 under a heavy load.

It sounds like the problem is independant of your gpu and gpu drivers so at least that narrows down the potential causes. My Phenom II seems to throtle itself at below the 62 degrees that AMD claim it can tollerate, in fact it happens at about the 55 degree mark if I remember right. I'm not sure how tough it would be to re-disable a core or two to bring the temperature down to the mid-40's, alternatively you could downclock and undervolt it to about 3GHz to lower the temps without destroying performance in order to eliminate premature cpu downclocking as a potential factor.

my CPU is the phenom ii x2 555 i always have it unlock to 4 cores i never had a problem when its unlock until now the CPU was the causes of the problem when its unlock my games start to stutter CPU usage 100% when its happening and i think i know why its happening during the summer the CPU was running hot i guess it was too hot I bought a new CPU cooler you can see it on the link here http://www.newegg.com/Product/Product.aspx?Item=N82E168... but i guess it was too late the damage is done if you guy know any ideas why this is happening please let me know can all so Help people who's having the same problem..

Those temperatures with the new cooler look ok. I don't think you damaged anything, the cpu should throttle before you actually damage it. You might be unlucky in that you got an x2 which unlocks to an x4 but where one or both of the cores which were locked are defective and produce errors under stress (I'm not sure if that would produce the problem you're describing). You might want to try running a prime95 torture test on it to see if it encounters any errors.

From your description of the problem, my guess would still be something overheating rather than a defective core. What kind of case do you have and how well ventilated is it? If your gpu is consistently seeing 85deg, your other components might be starved for air and could benefit from another fan (my 6870 with reference cooler never exceeds 75deg). You should blow all the dust out of the heat sinks if you haven't already, then temporarily open your case and point a room fan at the motherboard to check if something on it is overheating.

Ok im running prime95 right now i'll let you know what happens when its done.. i tried unlocking it to a x4 again this time i under clock it to 2.8GHz when im playing Battlefield the game still lags but this time it takes longer to start happening drops down to 12FPS for 15 sec or so then back to 60FPS but when its on x2 doesn't happen at all

This is my case link here: http://www.newegg.com/Product/Product.aspx?Item=N82E168... : I have one 120mm rear fan and another 120mm fan at the front which blows air from the outside to in the case. and the video card i called XFX customer service and ask if the 6870 running to hot at 85c they say its ok the card is design to run that hot at 30% fan speed if the card temperature to reach above 90s the fan speed would go up to keep it at the 80s mark.

The fact that the problem disappears when in x2 mode would lead me to believe that there is something wrong with at least one of the locked cores. If you can, it might be worth it to unlock one core, test it then unlock just the other core and test again to see if one or both of them is affected.

That gpu temp should be fine, lots of folks (myself included) tend to shoot for the lowest possible temperature but you're still well within spec so I wouldn't worry.

I followed the link you posted to your case and from what I can read off the power supply label, it lists

+12v = 16A
+5v = 35A
+3.3v = 20A

Since V*A=W you've only got
192 Watts on the +12v rail (where most of the load is in a modern computer)
175W on the +5v rail (where most of the load used to go ~10 years ago)
66W on the +3.3v rail

I think this is cause for some concern. I believe that this is an older power supply design from when most of the load was applied to the +5v rail. In a modern computer (yours) the majority of load is applied to the +12v rail so a modern power supply can deliver most if not all of its rated wattage through the +12v. Here's a link to a modern, reasonably priced, psu with about the same wattage as yours

http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...

it lists 2 +12v rails, one at 16A and one at 17 for a combined total of 384 watts on the +12.

With your current setup your video card has the potential to draw about 150W and your cpu another 80W for a total of 230W which is already well above your power supply's max of 192. That's not to say every time you play a game you're exceeding the limits of the psu but I wouldn't dare run your setup with that supply, frankly It's a time bomb which could take out the rest of your components if/when it goes. If I were you, my first priority would be to replace it with a better quality unit. The unit I linked earlier is popular for lower power systems like yours. Antec, Corsair and Seasonic are 3 reasonably well respected psu makers. It's usually prudent to read a few review before you buy because even the most reputable manufacturers occasionally make a bad product. hardwaresecrets.com is a favourite of mine for psu reviews. Newer power supplies tend to have much better efficiency as well which will save you (some) money in the long run.

That's certainly a step in the right direction. I haven't heard great things about Raidmax but if the problem started before you switched psu's and continued afterward then you can at least rule that out as a problem.

If you set Pirme95 to run a torture test it will only stop when it encounters an error or when you tell it to. I take it you're testing all four cores at once? If you are and none of the 4 threads have stopped due to error for a few hours then you can probably rule that out as a problem. If you monitor the processor frequency with cpuZ and while it's running prime95 you see the frequency drop from 3200MHz to 800MHz for a few seconds, then climb back up to 3200 that probably means the cpu is throttling itself. What are your temps at with prime95?

Unfortunately, if the 2 cores visible from the factory work, then AMD have lived up to their end of the bargain. By unlocking the other 2 you are running the processor outside the recommended specs and so have voided your warranty. AMD makes no claim that the locked 2 will work, in fact when P2 was first released the x2's were really x4's with 2 defective cores just as x3's were x4's with 1 defective core. As yields got better, there was still demand for the x3 and x2's so AMD started to disable useable cores which is why unlocking is a gamble at best. You don't know if yours has defective cores or just disabled functional cores.

I looked it CPUZ while Pirme95 is running and your right the frequency drop from 3200MHz to 800MHz for a few seconds then climb back up this like you said i looked at task manager all 4 cores are at 100% usage do you think if i disable cool and quiet will help?

That behavior sounds typical of a cpu throttling itself due to temperature. I'm not too familiar with the whole core unlocking process or the program you're using to monitor temps but it looks to me like the CPU temperature sensors are not being read. If I remember right, the temperature Everest is reporting is typically higher (with a higher limit) than the ones it's not (limit ~62deg), so if that's the temperature the motherboard is using to determine throtling it could be the cause of the problem. Did you notice the cpu temperature before this problem started? Did it suddenly stop reading or has it never read after you unlocked it?

What worries me a bit is that MCP temperature. According to google it's the southbridge combined with a couple other chips all on the same package. Other people reported similarly hight temperatures so it's not unheard of but some of the motherboards with this chip come with small fans specifically to cool it. It might improve stability to add a small fan blowing across it.

I would set it back to x2 mode and run prime95 while monitoring the temps and frequency again to see if you see the same frequeny drop and high MCP temp are observed. My guess is that the temp will stay high but the frequency will hold steady.

unfortunately when the CPU is on x4 mode you can't read the temperature (EVEREST Ultimate Edition) is the only program i cant find that gives you any short of reading on the CPU temperature any other programs will this say (0c) when i first got the CPU i looked it up on Google and apparently that's normal you cant read the temperature of a AMD CPU when its unlock :??:  with the MCP temperature its always bin that high (x2 or x4 mode). the CPU temperature (CPU 49 °C 120 °F) used to be higher then that with the old CPU cooler it got up to (55c) and that's before the problem started. the maximum temperature it can handle 70c but I think that's only when it in x2 mode

like i said try turning off power saving mode in bios and the desktop power settings.
what your refering to is amd's powesaving feature... they dont have thermal control per'say the power isnt reduced because of temps its reduced to save energy. basicaly the cpu multiplyer halves and the core volts drop. this helps reduce temps and increase system efficiency...

you can turn it off in bios or you can adjust how intrusive it is in the powermangment options in windows. the best bet is windows. just set the idle cpu usage to +5 percent and the max cpu usage to 100 percent. this way power saving wont enable unless the cpu is below 5 percent usage...

sorry i didnt explain it clearer the first time.

nor did i say disable vsnc... i was on about time sync. where your clock syncs with the atomic clock to get the acccurate time.. not vsync on the monitor timing. time sync can interfear witgh some games.
